    Hello.
    I recently downloaded the Unity Hub application, but when I attempt to download and install any of the betas versions, the download goes fine (I guess, since downloading something is harsh with my Internet, 300 Kb/s), but when it comes to installing, it instantly shows the "Installation failed".
    In the components list, I diabled MVSC, since I already own MonoDevelop.

    Hi,
    Sorry to hear you are having troubles installing the editor.

    Can you try installing only the editor first ?
    If all goes well, could you try adding the required components after?

    Thank you for your help.

    I had the same issue as the op. I solved it by following your instructions but I had to close the hub application then restart it for your instructions to work and it would stop working after every component or 2 that were installed; so I had to close out of the hub app several times and repeat the process several times until everything was downloaded and installed.

    Sometimes the download would fail, sometimes the install would fail and it would say, "the file was corrupted."
    I restart the hub application, add one component at a time til it breaks again, then repeat the process until all components downloaded and installed successfully.

    Happening right now with my 2018 2.7f1. On windows 10 64b.
    - UnityHub 0.20.1

    Also when trying to install via Unity3d installer, nothing happens after the windows admin popup.

    Hello @HouseHoStudio and @HanSolar.
    Can you report a bug in the Hub, please? You can now report a bug by right-clicking on the tray menu icon and selecting "Report a bug".

    Thank you

    I just discovered that if you set Windows Security "Exploit protection" settings "Force randomization for images (Mandatory ASLR)" to ON, that the Unity Hub installer always fails with this error. Turning it OFF (which it is by default) fixes the issue.
